| 2. Create customized validate criterions by entering value in text input like, 'Max Value'. |
| 3. Create customized error message by entering value in the error message text input. |
| 4. Input a number in the text input at bottom to validate. |
| 5. Validate the inputted number by making focus out of the text input. |
| 6. If the data entered is invalid, default error message in red will be shown if user did not customize their own one. |
| The customized error message will be shown if user already set one. |
